Andy 5 These have supports on both the front and back of your wrist making them much better than the previous wrist protectors I owns. The fit is very good too. I bought the M size for my 6 year old, but I can also squeeze them on my hands, thanks to the elastic and velcro design. I'm actually going to buy the L size for myself as I've injured my wrist and I want to wear it with ice packed inside.
